Electrical Panel Upgrade, Replacement & Installation in Kansas City
Kansas City's housing runs from 1920s bungalows to brand-new Northland builds, and the panel behind the cover tells you which era you're standing in. We replace fuse boxes in Waldo and full 200-amp services on new construction, and the job looks nothing alike.

A different panel on every block
In Brookside and Waldo we still find knob-and-tube remnants feeding a panel that was upgraded once in the 1970s and never again. Around Westport and the Crossroads, converted and subdivided buildings often have service that was never properly re-sized for how the space is used now. Newer Northland construction usually has capacity but sometimes no free slots. The one constant across all of it: nobody regrets going to 200 amps, and plenty of people regret not doing it while the wall was open.


What panel replacement or installation costs in Kansas City
Every job gets a flat price once we have seen it, before any work starts. These are the things that move it, and which way.
| Job | Relative cost | What drives it |
|---|---|---|
| Like-for-like 100A replacement | Baseline | Same service size, safer panel. |
| 100A → 200A service upgrade | Higher | New panel, meter socket, and service entrance conductors. |
| Fuse box or knob-and-tube era | Highest | Older Brookside and Waldo homes. Mast, grounding, and sometimes branch circuits need bringing up to code. |
| Sub-panel addition | Lowest | Detached garages, basement apartments, workshops. |
| New panel installation | Varies | A residential electrical panel for a new house or an addition, sized from the load calculation before the walls close. |
Older housing is where the variation comes from — if the mast, meter socket, and grounding all need replacing alongside the panel, that's the most involved version of this job. We price it flat after seeing it.

Questions We Get in Kansas City
Is a breaker box the same as an electrical panel?
Yes. Breaker box, breaker panel, service panel, load center and electrical panel all mean the same box: the one where every circuit in the house starts. Breaker box replacement or installation is the same job as a panel replacement or installation.
Do you install residential electrical panels on new houses and additions?
Yes. We wire new houses and additions for builders and homeowners, and the panel is sized from a load calculation for what the house will actually run, with spaces left for an EV charger, hot tub or heat pump later. Making room later usually costs more than leaving it now.
Can you repair an electrical panel instead of replacing it?
Often, yes. A failed breaker, a loose or burned connection, a corroded main lug or a damaged cover are all repairs. Replacement is the answer when the panel is a brand with a known breaker problem, the bus itself is burned, or there is simply no room for the circuits the house needs. We tell you which after opening it.
How much does it cost to replace an electrical panel in Kansas City?
Same-size replacements are the least involved. A 100A to 200A upgrade costs more, because the meter socket and service entrance conductors change with it. Older homes in Brookside or Waldo with a fuse box or knob-and-tube wiring add to any of those — the mast, grounding, and sometimes branch circuits need work alongside the panel.
What does a 200 amp service upgrade involve?
More than the panel. Going from 100 to 200 amps replaces the panel, the meter socket, the service entrance conductors and usually the grounding, and on an overhead service often the mast and weatherhead too. Evergy disconnects and reconnects the power, the city inspects, and the whole thing is typically done in a day.
Is an electrical service upgrade the same as a panel upgrade?
Not always. A panel upgrade can be a same-size swap: a new panel on the same 100 or 200 amp service. An electrical service upgrade raises the capacity coming into the house, which changes the meter socket and the conductors from the utility as well. We tell you which one your house actually needs.
Do I need a 200 amp service?
If you have central air, electric appliances, and any plans for an EV charger or hot tub, almost certainly. If you're in a small home with gas heat and no plans to add load, 100A may still be fine. We'll give you the honest answer.
What's wrong with knob-and-tube wiring?
It has no ground conductor, the insulation degrades over decades, and it was never designed for modern loads. Many insurers won't write a policy on a house that still has active knob-and-tube circuits.
Do Federal Pacific or Zinsco panels have to be replaced?
Both have a long record of breakers that fail to trip under fault, and neither has been manufactured for decades, so replacement parts are salvage. Home inspectors flag them, and some insurers will not write a policy until the panel is changed. If you have one, replacing it is the fix — there is no repair that makes the panel current again.
How long will my power be out?
Typically four to eight hours, in a window coordinated with Evergy ahead of time.
Do you do panel work in Johnson County, Kansas?
Yes. We hold a Johnson County, KS electrical contractor license as well as our Kansas City, MO license, and we pull panel permits in Overland Park, Olathe, Lenexa and Shawnee as well as on the Missouri side.
Which electrical code does Kansas City inspect panel work to?
The 2017 National Electrical Code. Independence, Lee's Summit and Blue Springs are on the 2023 edition and Gladstone on the 2020, so the breakers a panel quote needs can differ across a city line. We price to the code the permit falls under.
Is a breaker box the same thing as an electrical panel?
Yes. Breaker box, electrical panel, service panel and load center are four names for the same box. In Kansas City's older neighborhoods it is sometimes still a fuse box, which does the same job with fuses instead of breakers. Replacing any of them is the same job, priced the same way.
